l/Vestinghouse or other coupler terminal of the proper train pipe. Thisprovides for revolution of the section carrying the coupler asdistinguished from rotation of the tube within the head and givesrevolution about the joint and in a plane instead of the conical path ofmovement which is caused by swinging a diagonally placed coupler aboutthe end of the pipe.

My illustration is intended to be conventional in that the head, tube,supporting mechanism pipe joint and coupler parts shown are selectedfrom among various such parts capable of use with my invention and thatthe individual types of this mechanism shown need not be used topractice my invention.

In Figure l the head 10 is secured by bolts 11 to a yoke 12 whichstraddles a block 13 at the lower end of the bracket 14 carried by anyfixed car part 15. The rear 16 of the yoke is adapted to be pressedagainst the back face 17 of the block 13 by a spring 18 held to its dutyagainst the rear face of the yoke by a bolt 19. This bolt is securedwithin the block 13 at one end and carries a nut 20 and washer 21. Thisgeneral form as so far described is shown in a copendingapplicat onfiled by Edward A. Robinson for connecter for train pipes Serial Number412,645, filed September 25, 1920, and is one only of many constructionswith which my invention may be used. n

As in the Robinson application, the head is shown as having forwardlyspring-pressed connecter tubes 22 which carry gaskets at their forwardends at 23;. and which, are pressed forwardly within recesses 24: bysprings 25 abutting against collars 26. The tension and extent of normalprojection may be adjusted by nuts 27 with any desired locking mechanismfor them. I

In the Robinson construction each tube is free to turn about its axisand the pipe coupler parts connect with the head and swing with the tubeabout the axis of the tube. lVith the relatively low pressure of thesesprings 25 this is entirely feasible when the connecters are not unitedto the connecters on other cars, but with additional spring pressure theturning of such a tube becomes This is so far true that in oneconstruction. where a tube through the head is subjected to the axialpressure of the main connecter spring, it was found impracticable tomake it turn in the head.

However, the rotation of the tube for the purpose of swinging thecouplers for the pipes about the tube axis presents the two difiiculties that the tube cannot be turned while the pipe is under pressurefrom connection with another car and that the parts carried by it swingthrough the path corresponding to the surface of a cone twisting thecoupler at the same time that it revolves about the tube.

With my construction I avoid rotation of the tube and even accidentalswinging of the parts carried by it about any axis of the tube bypreventing rotation of the tube.

One method of preventing the rotation of the tube is shown in Figures 3and 4 where it will be seen that a key 28 is fitted into the head 10 andis splined into the tube so as to allow longitudinal play of the tubewhile preventing rotation.

In Figure 5 another means of preventing tube rotation is shown asapplied to the middle tube. in it the head 10 is mounted upon aresiliently held tubular support 29 keyhole-slotted at 30 so that theangularlyextending fitting 31 and other parts can be inserted forassemblage but cannot swing with the tube. The tube is here screwed intothe fitting by a spanner wrench.

I insert a joint conventionally shown at 32 between the part 33connected more directly to the tube and the part 34 rigidly connected tothe half coupler 35 interiitting with the half coupler 36 carried by thetrain pipe hose 3?. I

By this construction the rigid section 38 swings about the joint in adiagonal plane which is always the same and which may be selected tobring the two half couplers together to the best advantage withoutrequiring torsion of the train pipe.

Two forms of joint are shown in Figures 7 and 8. In Figure 7 the parts33 34 are duplicates except for the bolt-receiving construction and thatone carries a ring 39 and the other a groove #10. Packing 41 assists informing the seal.

T he spring bolt 42 is secured to one of the parts at one end, is coiledat 13 to. give it longitudinal spring and passes through the other partto a "nut 44 resting upon packing 45. A cap l6 covers the nut andpacking and may itself be fluid-tight.

In the other joint the parts 33 34 meet in opposing flanges a7, 48,spaced by packing a9. One of the flanges is threaded to receive a cap 50which engages the other flange also to draw the flanges together.

It will be evident that various changes may be made by others interestedin obtaining part or all of the advantage of my invention withoutcopying it and it is my purpose to include herein all such changes ascome within the reasonable spirit and scope of my invention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1.
